Diesel Fuel System Layout

Description of a modern diesel fuel system as a standby energy source.

Diesel fuel system layout.

Introduction to fuel supply system for ci engines. When designing fuel oil systems remember the following. In early fuel oil system designs boilers were the primary user of the fuel. Diesel engines rely on the air fuel mixing being done in the cylinder which means they need a fuel injection system.

The fuel supply system of a diesel engine can be called as the heart of the engine since the engine performance directly depends upon the proper functioning of this system which must supply meter inject and atomize the fuel. The main components of the fuel system in diesel engine are. Combustion in a diesel engine occurs when this rush of fuel is mixed with hot compressed air. The function of the diesel fuel system is to inject a precise amount of atomized and pressurized fuel into each engine cylinder at the proper time.

Foreword this section of the application and installation guide generally describes diesel fuels and diesel fuel systems for cat engines listed on the cover of. Provide foot valves to maintain pump prime anti siphon valves to prevent accidental leakage and fusible link shutoff valves for fire safety. No electrical spark is used as in a gasoline engine the fuel system consists of the following components. When calculating pump suction lift assume the worst case scenario i e a nearly empty tank.

The modern diesel fuel or fuel oil systems are used differently than systems designed a decade or more ago. The fuel is injected directly into the combustion chamber which can be either a segmented combustion chamber known as indirect injection idi or an unsegmented combustion chamber known as direct injection di.
